When your project calls for roofing that combines structural strength with a finished, professional appearance, PPGI Roofing Sheets from Astal Roofing Industries are the answer. Pre-Painted Galvanized Iron (PPGI) sheets deliver the corrosion resistance of galvanized steel with the added advantage of a factory-applied paint coating – making them a preferred choice for architects, EPC contractors, and procurement teams who need both performance and aesthetics in a single product.
What Are PPGI Roofing Sheets?
PPGI stands for Pre-Painted Galvanized Iron – a steel sheet that undergoes hot-dip galvanizing followed by a precision coil-coating process where paint is applied under controlled factory conditions. The result is a roofing sheet with a uniform, durable finish that resists fading, weathering, and surface degradation far better than site-painted alternatives.
Unlike sheets painted on-site, PPGI sheets come with a consistent coating thickness and adhesion quality that field application simply cannot replicate – giving procurement teams confidence in long-term performance without added maintenance cost.
Key Features & Technical Advantages
Precision Thickness Range
Range (0.40 mm – 0.60 mm) Multiple gauge options to match structural load calculations – whether for light commercial roofing or heavy industrial applications requiring greater rigidity.
Top Coating
15–20 Microns The exterior-facing paint layer is applied at 15–20 microns – thick enough to provide long-term UV resistance, colour retention, and surface protection against rain, humidity, and airborne pollutants.
Back Coating
5–7 Microns The reverse side carries a 5–7 micron protective coat that guards against condensation, underside corrosion, and chemical exposure from the building interior – often overlooked but critical for long-term sheet integrity.
Fade-Resistant & Weatherproof
Eco-Friendly & Recyclable
Available in Custom Sizes & Colours
Where Are PPGI Roofing Sheets Used?

Why Choose Astal Roofing for PPGI Sheets?
At Astal Roofing Industries, our PPGI Roofing Sheets are manufactured using coil-coated steel sourced from established primary producers, processed at our Bengaluru facility under strict quality controls. Every batch is checked for coating thickness, adhesion strength, colour consistency, and dimensional accuracy before dispatch.
We supply to EPC contractors, builders, and procurement departments across India, offering consistent quality on repeat orders – so the sheet you approved in the first delivery is the same standard you receive in the tenth. Our team is available to assist with product selection, specification matching, and logistics planning for large or time-sensitive projects.
